What is the value of a misprinted 10 Dollar bill that is missing the serial numbers and the two fed stamps on both sides of Hamiltons pic.?

Depending on what's on the other side of the bill, you could have either of 2 errors. Both are related to the fact that bills are printed in multiple steps, each one adding different parts to the design.

If the back side has images of the seal and serial numbers, it may be a "flipover" error that happened when a sheet of paper accidentally was flipped over during the printing process so the seal, etc. were printed on the wrong side. Flipovers can retail for $300 or more.

If there's no seal or numbers anywhere, the sheet of paper the bill was printed on was accidentally left out of the step that adds those features. I haven't seen specific prices for this error but it seems reasonable that it would be in the same range as a flipover.
